muscle-arterial pumps for the veins and lymphatic ducts
Lymph is the fluid that surrounds all tissues. Important cells in the lymph are lymphocytes and macrophages. Importance of lymphocytes and macrophages lays in that macrophages absorb or better say eat foreign microbe, on the other side lymphocytes increase their number. Lymph is part of the lymphatic system and flows through lymphatic vessels and lymph nodes. Lymph have the function of removing foreign microbs to lymph nodes and return proteins to the blood. Lymph move across lymphatic vessels simply because of activation surrounding muscles and because of that pressure is different than in blood vessels [1]. Problems that lymph may cause are primarily because there is no pump like blood have [2].
Lymphatic flow


Physiotherapy had a crucial part in resolving problems with the lymph using the technique lymphatic drainage and exercise [3],[2], [4]. Exercise induces transport of lymph. We can say that any movement of muscles and artery pulse cause the transport of lymph in the lymphatic system. Benefit of active life is that our body induces activate inactive and inches late lymph vessels. Some activities that are recommended are swimming, brisk walking, tennis, jumping, gymnastic, deep breathing, etc [5], [6].

Parts of lymphatic tissues, hydrodynamics and lymphatic transport

We have several parts of lymphatic tissues lymph nodes, spleen, lymph vessels, thymus, lymph ducts [7]. In some literature has described two types of lymph pumps: intrinsic and extrinsic. Extrinsic lymph pump are muscle, arterial and respiration. Intrisnsic lymph pump are contraction of lymphatic vessels. There are two existing types of pressures near atmospheric and negative relative pressures. The peripheral lymphatic network has lower pressure than final tracts and average lymph pressures are lesser than the venous network where lymph finally flow [8],[9].
